I really love "artifact stories" which have the protagonists explore and try to figure out some abandoned alien relic/vessel/installation, so the metropolis+graveyard stuff tickles me personally as well.
How was Crucible? I haven't read any TOS by DRGIII yet.
Yeah, I like that, too. It's kinda like Indiana Jones, with the artifact exploration, or for a more Trekkish analogy, it's similar to Christopher's The Buried Age. (Awesome book, by the way).
I've never read the Crucible trilogy, so I couldn't tell you. The only books I've read by DRGIII are the very epic Serpents Among The Ruins and his Typhon Pact books.
